It seems to me, that the e1000 works as it should. For your
information:

/proc/pci:

  Bus  0, device   7, function  0:
    Ethernet controller: Intel Corp. 82540EM Gigabit Ethernet Controller (rev 2).
      IRQ 23.
      Master Capable.  Latency=64.  Min Gnt=255.
      Non-prefetchable 32 bit memory at 0xfb040000 [0xfb05ffff].
      Non-prefetchable 32 bit memory at 0xfb020000 [0xfb03ffff].
      I/O at 0x2440 [0x247f].

lspci:
